Currently the utime() is done by kio_file when copying from local to local, indeed.

Doing it from file_copy, when doing a get() and a put(), sounds impossible. It's too
low-level. It could be done from CopyJob, since that one lists the sources (or stat()s
it, for a single file), so it knows the atime/mtime. We would need a new 
special() call (or a better named call in KDE4) to set the atime/mtime over any
protocol.... It's mostly for kio_file as destination though.
Is that enough information for the patch you're about to write? :-P
